When customizing Axiom speakers, you have a section titled "Audio Jewelry", with two options

1. Standard or Die Cast woofers2. Standard or Biwire/Biamp inputs

On most tower speakers nowadays, biwire inputs are quite standard it seems. Why is it only an option? And why under a section called "Audio Jewelry"? Are they saying these two options provided are for aesthetics only?

I've been doing some reading on bi-wiring and have read SOME articles claiming that to "truly" biwire/biamp, the crossover must be removed or modified or something?

If I bought M80's with dual inputs, wouldn't feeding them 120 watts down one speaker wire and 120 watts down the other mean I'm feeding the speaker a total of 240 watts? As opposed to single input...then I'd only be feeding them 120 watts total.

I do preffer the appearance of the cast over the stamped basket.I've read it doesn't make a differnce with audio quality and I can't say either way.Theres no doubt in my mind that the cost of going cast is worth it.I consider my speakers an investment, one that should look as good as it sounds.

Take the hint that the title of that section is giving us: neither of the options results in an audible improvement and they're there to satisfy the misconceptions of the misinformed/uninformed. Andrew touched on the stamped/cast frame point here .

On the inputs, you can't "feed" a speaker any more power than it needs at any given instant in time to play at the needed volume level(typically about 1 watt at a comfortably loud average level). The maximum needed on a brief peak is much more, of course, but the capacity of the amplifier's power supply section is the limiting factor, and feeding that same supply through two wires rather than one can't double the max available or increase it in any amount.

In the day's of yore, bi-amping was common. True bi-amping would mean a separate and dedicated amplifier for the lower bass frequencies and another for the tweeters and mids. The tweeter's and mids use much less power than the woofers to produce similar perceived volume levels. When you order the bi-amp option there is a connector between the 2 sets of speaker posts , these are removed when you are bi-amping , thus nothing is needed to be done to the crossover as it has already had the Mid/tweets separated from the bass portion of the crossover. These days most people use a subwoofer with a dedicated amp , and as such the requirement put on your main amp is much relieved , making bi-amping pointless and expensive. The guys out there who say interconnects and speaker wire make a difference are going to disagree with this position, so I guess what matters is which camp you are in.

As for cast baskets, Ian has done extensive testing and has proven to his satisfaction that cast baskets are not necessary and are eye candy. I personally believe that small drivers do not benefit from cast baskets but large bass drives do. I think there may be a small advantage in heat dissipation but have no way to prove it. All my car audio subs that I buy have cast baskets based on my preference'.

Lightweight, alloy wheels are actually a performance enhancement to a vehicle. Provided, that is, they are actually lighter (going from a 17" steel wheel to a 20" alloy probably isn't going to help). When removing weight from a car unsprung, rotating mass (tires, wheels, brake discs*) offers the most improvement for the least decrease.

*Some high performance cars move the brake disc "inboard", that is they sit on the sprung side of the suspension, and use the axles to slow the wheel rather than being bolted directly to it.

Lightweight, alloy wheels are actually a performance enhancement to a vehicle.

this is very true, in fact when building a track car this is one of the first changes that are made to a stock car, as it is the easiest thing to do to get perceived horsepower back... Then, you strip the interior. However, reducing rotating mass has a multiplier of 3 over what a static load is.. But then again, an average interior weights about 3-400lbs...

I got cast drivers in my LFR's because i wanted them, and they weren't that expensive to add... Even though from a material science point of view, there is no difference. The more folds you put in a sheet of metal the more ridged it becomes, and a combination of the thickness of the initial metal used as well as the number of bends/radius/location will determine the final rigidity of the manufactured piece.

Since Axiom uses a relatively thick piece of sheet metal to begin the process with that is a wonderful starting point, then they press the piece which has multiple folds to add rigidity.. Oh, wait... I'm rambling again....
